SASL - Burd IRC currently only supports SASL Plain. We are currently working on adding more SASL authentication mechanisms such as external.

SSL/TLS - Burd IRC supports connecting to IRC networks using SSL/TLS. It was not working in previous public betas of Burd IRC but should be working on the latest version.

Server passwords - Burd IRC supports the ability to connect to passworded servers. Which also enables the capability of logging into ZNC without having to manually /quote PASS. Easier ZNC setup such as being able to enter ZNC username, password, and the network without having to type in the whole PASS command as a server password will be a possibility for a later version.
